Inventor: SCHOLLY WERNER
IPC: G02B6/42
Filed: 1989-04-19
Abstract: A variable traffic sign (1) (Fig. 2) has a light source (2) having a concave mirror (3) as well as an optical fibre bundle (6) which ends with its input end at the light source (2) and with its output end with individual fibre strands (9) at a front plate (3), the ends forming light points. In order to compensate tolerances of the individual components occurring within the light transmission path, and in order to achieve overall a good uniformity of the represented sign, a measure is provided that the end region of the optical fibre bundle on the input side is constructed with its individual fibre strands (9) running together at an angle to the optical input end. In this way, a largely homogeneous injection of the beam into the individual fibre strands is achieved. On the output side, the light emergence angle for each light point can be set individually so that intensity differences can be compensated here once more in a simple way. <IMAGE>

Abstract: An improved vehicle height sensor and automotive leveling system (90) are described using, in a preferred embodiment, two optical emitter-receiver pairs (44,46) mounted in the sidewall (22) or dust cover of a standard automotive air shock (40). The emitter-­receiver pairs (44,46) are arranged to operate by reflecting light from the central shaft (16) of the shock absorber (40) . Each emitter-­receiver pair (44, 46) provides a light path (52,53) that lies in a plane substantially perpendicular to the extension direction (28) of the shock (40). The two emitter receiver pairs (44,46) are spaced apart along the extension direction (28) of the shock (40) . Movement of the internal piston (18) of the shock (40) successively interrupts (by absorption) the light paths (52,53) of the emitter-receiver pairs (44,46) so as to provide a positive indication of the location of the movable piston (18) and hence the height of the shock (40) and the height of vehicle body above the road. The emitter-receiver pairs (44,46) are mounted in a common assembly (60) and seal to the shock dust cover (22) through a single hole. They are convenient to manufacture in a single module (42) which includes the control logic (93) needed to add or remove fluid from the shock (40) to maintain it in the reference position independent of the vehicle load. This makes possible a particularly compact unit.

Abstract: The present invention obtains enthalpy rise deviations in core power distribution using core exit thermocouples 18 and an inlet temperature detector 20. The enthalpy rise deviations are used to determine rod position change relative a rod reference position. Because rod position change is linear with respect to enthalpy deviation, the change can be determined from the slope using the deviation. By adding the change to a reference rod position the actual rod position can be determined.

Abstract: Improved compositions and methods for selective access to tumor regions (or other regions of abnormal endothelial properties). This capability provides powerful contrast-enhancement agents for nuclear magnetic resonance imaging. A polyatomic complex which includes intramolecular ferromagnetic coupling between metal atoms is associated with a polymer or microsphere carrier matrix which will bind to endothelial determinants. A solution containing this carrier complex is injected into a human (or other) body to be imaged. The carrier complex will preferentially extravasate at locations where the blood vessel walls have increased porosity or microvascular surface changes, and especially at tumor sites. Thus, the changes in relaxation time induced by the presence of the carrier complex will provide a high-gain marker for magnetic resonance imaging. 
     Multiple superparamagnetic polyatomic complexes are described, including novel complexes which include acetate and glycinate bridging ligands with a polyatomic metal-atom-complex core.

Abstract: A throttle valve unit 6 is provided on the side of either of two rows of engine cylinders. Two intake air passages of different length lead to the two cylinder rows 2 and 3, the passage for the first cylinder row 2 having a first resonance portion 18 and the passage for the second cylinder row 3 having a second resonance portion 19 nearly equal in length to said first resonance portion and a pressure wave inversion portion 20 extending from said second resonance portion at least to the upstream-side end 17 where said two passages separate from each other and having a cross-sectional area that allows inversion of intake pressure waves. 
     The effects of resonance supercharging in the two resonance portions are nearly equal, and the volumetric efficiency shows only one peak in low engine speed corresponding to the occurrence of resonance supercharging. Therefore, the deviation of intake air distribution is minimized and the variations of generating torque from the cylinders are reduced.

Abstract: A method for NMR spectroscopy metabolite imaging utilizes the steps of: applying to a desired portion of a sample a pulsed phase-encoding linear magnetic gradient signal in at least one of the three orthogonal dimensions of a Cartesian coordinate set, prior to acquisition of free-­induction-decay NMR response signals from the sample por­tion; substantially eliminating from at least the sample portion eddy current fields induced responsive to the phase-encoding gradient pulses; maximizing the signal-to-­noise ratio of the NMR response signals; and displaying the data resulting from Fourier transformation of the received response data. A high-field imaging system is provided with self-shielded gradient coils, to substantially remove eddy-current effects, and at least one of maximized-SNR antenna, of quadrature-driven volume RF coil and/or surface RF coil types are utilized for both transmission of the excitation RF pulses and reception of the RF response signals. The acquired FID data is filtered and a Fourier transform reconstruction, of dimension  d ′ equal to one greater than the number  d  of spatial dimensions to be displayed, is performed.

Abstract: A semiconductor device having an improved protection scheme and a temperature compensated sustaining voltage is provided by integrating a plurality of temperature compensated voltage reference diodes 28 and 71 between the drain 22 and the gate 20 of the semiconductor device. The diodes 28 protect the device by clamping the device's sustaining voltage to the total avalanche voltage of the diode. The device will dissipate any excessive energy in the conduction mode rather than in the more stressful avalanche mode. In addition, the plurality of diodes will provide for a temperature compensated sustaining voltage of the semiconductor device. The plurality of diodes 28 and 71 are formed back-to-back in polysilicon 65. The positive temperature coefficient of the avalanching junction of each diode pair is compensated for by the negative temperature coefficient of the forward biased junction.
